Link to a Smart Contract You Deployed Means Understanding Smart Contract Deployment

Understanding smart contract deployment is crucial, and having a link to a smart contract you deployed is a key part of that process.

A link to a smart contract you deployed is essentially a unique identifier that allows others to access and interact with your contract. This identifier is often a hash of the contract's code, making it a permanent and immutable reference.

To generate this link, you typically need to deploy the smart contract to a blockchain network, such as Ethereum or Binance Smart Chain. This process involves creating a new contract instance, which is then stored on the blockchain.

Having a link to a smart contract you deployed means you can share it with others, making it easier to collaborate and build upon each other's work.

A smart contract is a set of rules defined in executable code that governs interactions between organizations.

These contracts lay out the business model that governs all interactions between transacting parties, including terms, data, rules, concept definitions, and processes.

A smart contract can implement governance rules for any type of business object, allowing for automatic enforcement when executed.

A smart contract is a set of rules defined in executable code that governs interactions between different organizations.

These contracts lay out the business model that governs all interactions between transacting parties. They cover common terms, data, rules, concept definitions, and processes.

A smart contract can implement governance rules for any type of business object, making it possible to automatically enforce them when executed.

For example, a smart contract can ensure that a new car delivery is made within a specified timeframe, or that funds are released according to prearranged terms.

Smart contracts can be used to improve the flow of goods or capital, making business processes more efficient than manual human processes.

Smart contracts and chaincode are often used interchangeably, but they have distinct meanings. A smart contract defines the transaction logic that controls the lifecycle of a business object contained in the world state.

Think of smart contracts as governing transactions, whereas chaincode governs how smart contracts are packaged for deployment. A smart contract is defined within a chaincode.

Multiple smart contracts can be defined within the same chaincode. When a chaincode is deployed, all smart contracts within it are made available to applications. A chaincode is a technical container of a group of related smart contracts.

A smart contract is a domain-specific program that relates to specific business processes.

Deploying and verifying your smart contract is a crucial step in the development process. You can deploy and verify your contract at the same time by running a command that includes your private details.

The remapping array helps with routing import statements in your contract to the right lib source. This is especially useful when working with complex contracts.

To deploy and verify your contract, you'll need to have your wallet public address, the deployed contract address on Polygon Mumbai, the deployment transaction hash, and other verification details like your Globally Unique Identifier GUID and verification status.

Deploying a smart contract in Starknet requires two high-level steps: declaring the class of your contract and deploying an instance of the contract class.

When declaring the contract class, you establish an initial owner by calling the class's constructor function. You can select the network by clicking the Starknet tab and then clicking the Remote Devnet menu.

To declare the contract class, click the Declare lib.cairo button. Remix's terminal will provide various logs with important details, including the transaction hash and class hash.

After declaring the contract class, you're ready to deploy an instance of the contract class. Simply paste the Devnet account address you used into the init_owner variable and click Deploy.

After deployment, Remix's terminal will display various logs, including a transaction receipt, containing important details, such as the transaction hash, contract address, and data.

Smart Contract Deployment is a crucial step in the process of creating and linking to a smart contract. To deploy a contract, you need to declare the class of your contract and establish an initial owner by calling the class's constructor function.

This process involves two high-level steps: declaring the contract class and deploying an instance of the contract class. You can use a development network (devnet) to deploy your smart contract, which enables quicker development and provides privacy prior to launching on testnet.

On a devnet, you can select a network, select a devnet account, and note its address for later use. The devnet account address is used to declare the contract class, which involves clicking the Declare lib.cairo button and noting the transaction hash and class hash.

Here are the key details you'll receive after declaring the contract class:

After declaring the contract class, you're ready to deploy an instance of the contract class. This involves pasting the devnet account address into the init_owner variable and clicking Deploy.

Deploying a smart contract on a development network, also known as devnet, is a crucial step in the development process. You can run a devnet as a local node, which enables quicker development than using a testnet.

To deploy a contract on a devnet, you need to declare the contract class, which involves sending the contract's code to the network. This step establishes an initial owner by calling the class's constructor function.

You can select the network by clicking the Starknet tab and then clicking the Remote Devnet menu. This will allow you to view a list of accounts specific to the designated devnet.

To declare the contract class, click the Declare lib.cairo button in Remix's terminal. You will receive logs with important details, including the transaction hash and class hash.

After declaring the contract class, you're ready to deploy an instance of the contract class. Simply paste the Devnet account address you used into the init_owner variable and click Deploy.

Here are the key details you'll receive after deployment:

Now that your smart contract is deployed on the development network, you can start interacting with it. You'll find the contract on the Starknet tab, under (3) Interact.

Once you're on the Interact tab, you can start testing and verifying the functionality of your contract. The contract is now operational and ready for use.

Interacting with your contract is a crucial step in the deployment process, allowing you to test and refine its functionality before deploying it to a live network.

Channels are a way for organizations to participate in multiple blockchain networks simultaneously, allowing for efficient sharing of infrastructure while maintaining data and communications privacy.

A channel provides a completely separate communication mechanism between a set of organizations, enabling them to coordinate independent activities when necessary.

Each channel member agrees to the parameters of a chaincode by approving a chaincode definition for their organization, which contains the parameters that govern how a chaincode operates.

The chaincode definition includes the chaincode name, version, and the endorsement policy, which specifies the organizations required to sign transactions before they can be considered valid.

In the example of the VEHICLE channel, the car contract specifies an endorsement policy that requires both ORG1 and ORG2 to sign transactions before they can be considered valid.

A sufficient number of organizations (a majority by default) must approve the same chaincode definition for it to be committed to the channel, allowing the smart contracts inside the chaincode to be executed by channel members.

The endorsement policy applies equally to all smart contracts defined within the same chaincode, ensuring that all organizations agree on the governance of a chaincode before using the smart contract to transact on the channel.

A smart contract is essentially a set of rules defined in executable code that governs the interactions between different organizations. These contracts can be used to implement governance rules for various business objects, such as a new car delivery.

Smart contracts can be used to automatically enforce rules when executed, improving the flow of goods or capital. For example, a smart contract can ensure that funds are released according to prearranged terms.

A smart contract can be invoked by applications to generate transactions that are recorded on the ledger. This makes the execution of a smart contract much more efficient than a manual human business process.

You can identify the owner of a contract instance by using the get_owner() function under the Read section. This function reads data and doesn't modify the contract's state, so it doesn't consume gas.

To use the get_owner() function, click the Call button, and leave the calldata field empty since it doesn't require any arguments.

The function will display the owner's address in the terminal, which is the address you provided during the contract's deployment in the constructor's calldata.

This is a crucial step in understanding the ownership and control of your smart contract instance.

To get price feed data from your contract, head over to Mumbai Polygon Scan using the link and paste your deployed wallet address in the search bar.

You'll notice you have proof of a verified contract.

Click on the contract Read Contract button and you'll find all the callable functions created in your solidity file.

Click on Connect to web3 to connect your MetaMask wallet, to be able to make the function calls.

Shardeum is an EVM-compatible or EVM-based smart contract platform, which means Ethereum developers can migrate their smart contracts without rewriting the code from scratch.

EVM stands for Ethereum Virtual Machine, and it's the architecture that gives Ethereum its value. This architecture is used by many other networks that customize it to fit their needs, saving them the trouble of reinventing the wheel.

First and second-generation blockchain networks like Bitcoin and Ethereum rely on an arduous consensus mechanism and self-imposed data limits to secure the network, which results in low transaction processing speeds. For example, Ethereum barely crosses 45 transactions per second, while a network like Visa can process up to 10,000 transactions per second.

Shardeum, on the other hand, is designed to process over 1 million transactions per second while maintaining high security and decentralization features. This is a significant improvement over current blockchain networks.

A ledger is essentially a record of transactions that update states in a ledger. It's what smart contracts interact with to store and retrieve information.

Smart contracts can access two distinct pieces of the ledger: the blockchain and the world state. The blockchain is where all transactions are recorded immutably.

Smart contracts primarily use three types of operations to interact with the world state: get, put, and delete. Here are what each of these operations typically do:

The blockchain contains an immutable record of all changes made to the world state, including those made by smart contracts.
